Abstract: PURPOSE: A structure of a multi-mode optical fiber for reducing a scattering loss is provided to improve a dispersive characteristic and a scattering characteristic by changing a structure of a multi-mode optical fiber. CONSTITUTION: A refractive index of a center portion of a core(21) is set up. A parameter is calculated to determine a size of the refractive index of a multi-mode optical fiber(20). An optimum core configuration factor is calculated to minimize the dispersion of an optical signal. A refractive index profile(24) of a peripheral portion of the core(21) is set up. A refractive index profile(23) of the center portion of the core is the optimum refractive index profile. The refractive index profile(24) of the peripheral portion of the core(21) is less than the optimum refractive index profile. A clad(22) is formed around the core(21). A refractive index of the clad(22) is less than the lowest refractive index of the core(21).

Abstract: A mobile terminal and a method for processing an event received in absence are provided to allow a user to check content of an event received in his absence associated with an event icon and quickly handle it, thereby displaying a function execution image by executing a function associated with an event icon when a user touches the event icon. A display unit(17) displays a standby screen and a function execution screen. A touch keypad(23) includes a plurality of key cells. A storage unit(15) stores an event icon associated with an event to be received. An event processing unit(22) stores an event received in the absence in the standby state in the storage unit(15). When a mobile terminal is changed from the standby state to an active state, an icon extracting unit(24) extracts the event icon associated with the event received in the absence from the storage unit(15). An event display unit(26) displays the extracted event icon at a key cell of the touch keypad(23). When the event icon is touched, a function executing unit(28) executes a function associated with the touched event icon and displays it on the function execution screen of the display unit(17).
